Hi WA,

I was out of office and home for three days.

Now tried your workaround for the "subtract from last item" problem with 
engine 2.6.2A2 (the latest one) on WindowsXP.

Using my test stack with 3 groups - the first two groups containing 2 
controls each, the third group is a nested one with 4 controls 
altogether - the result is that from each group the last control is left 
totally un-indented.

So your workaround - at least with my stack - seems to be only an 
approximation of a solution. Maybe there is indeed an additional problem 
with "subtract from".

My "new indenting routine" - see my post of Nov 26 - sidesteps both a 
possible "number of layers" or "subtract" problem, as it does not use 
these parameters and makes use of the "long ID" property instead - that 
lists all owners of a control.
